Product Description
Semi Truck In-Frame Box: Heavy-duty aluminum storage for professional truckers. Made in the USA by AMERICAN TRUCKBOXES ATB®
The A-IB52 aluminum semi truck in-frame box is purpose-built for owner-operators and fleet drivers who need secure, weatherproof storage mounted behind the cab on the truck frame. The smooth body and Diamond TP or Powder Coated Black lid provide a rugged, professional finish that holds up to daily road use. Every A-IB52 is manufactured by American Truckboxes LLC in Blanchard, North Dakota. Custom sizing is available for fleets with non-standard frame configurations.
Key Features
- DT-T-Handle Lock with stainless steel hardware: dual-action latch provides secure, pick-resistant closure that resists break-in on highway stops
- Stainless steel continuous hinge: full-length piano hinge distributes lid stress evenly and eliminates the failure points of short-segment hinges
- Smooth body aluminum construction: .100 aluminum walls resist dents and corrosion without adding unnecessary weight to the drive axle
- Diamond TP or Powder Coated Black finish: Diamond TP lid adds tread grip for stepping access; Powder Coated Black provides a clean, low-visibility appearance
- Rain gutter with bulb-type automotive door gasket: concealed gutter channels water away while the bulb seal creates a positive, weather-tight closure
- Internal door supports: keep the lid securely open during loading and unloading, preventing wind-slam damage
- Frame-rail mounting with included Mounting Kit M3100F: bolt-on installation positions the box behind the semi cab for easy access from the catwalk
- Step-rated lid design: box is built to support standing weight for accessing the back of the trailer

Q: What finish options are available on the A-IB52?

Powder Coated Black has a matte black painted finish suited for drivers who prefer a low-profile appearance. Select your preferred finish when adding to cart.
Q: How does the lid open and stay open?
A: The A-IB52 lid pivots on a full-length stainless steel continuous hinge and is held open by internal lid supports. The supports prevent wind from slamming the lid closed while you load chains, binders, or tools. The DT-T-handle latch locks the lid securely closed when not in use.
Q: Is this in-frame box weatherproof?
A: Yes. The A-IB52 uses a concealed rain gutter that channels water away from the seal, paired with a bulb-type automotive door gasket that creates a positive weather-tight closure. This combination keeps contents dry even in heavy rain or road spray common on highway routes.
Q: Does the A-IB52 include a mounting kit?
A: Yes. Each A-IB52 in-frame box ships with Mounting Kit M3100F, which provides the hardware needed for frame-rail installation behind the semi cab. The step-rated lid design allows drivers to stand on the box when accessing the rear of the trailer.
